Different fish require different water conditions. For a fish that requires a low or acidic water (such as the beautiful amazonian 'discus') or a fish that requires a high or alkaline water (such as the vivid 'electric blues' or 'yellows' from the Rift Valley in Africa)to be kept in water of the wrong pH would simply mean that the fish will probably be unable to breed, will never thrive and may have a much shortened life span.

How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.
Do alkalis have a pH less than 7?
no they alkaline solutions have a pH higher than 7
Weakest alkalis have a pH of?
10
Are alkalis and acids dangerous?
Acids and alkalis with a high pH (1 or 2 for acids and 14 or 15 for alkalis) can be dangerous, like hydrochloric acid which can cause damage to the skin if contact with the acid is made. Acids and alkalis with a low pH (5 for acids and 11 for alkalis) aren't dangerous, as vinegar is an acid with that pH and toothpaste is an alkali.
What makes alkalis alkalis?
Look on the pH scale. Below 7 are acids, above 7 are alkali's!! ;-)
Alkalis have a pH what than 7?
great then 7
List four properties of alkalis?
alkalis are corrosive, normally water soluble and are very soapy.
What is the pH range of solutions which are alkalis?
Alkalines, or bases, have a pH greater than 7 (maximum is 14).
What colours does ph paper turn in alkalis?
blue
Does Neutral mean safe?
Not really. On the pH scale of Acids and Alkalis, Neutral is the green colour at which a liquid is neither Acid nor Alkalis.
Which factors affect pH?
The three factors that affect soil fertility are the commercial fertilizers that add nitrate, potassium, and phosphorus to their soil.
Does pH have an affect on goldfish growth?
Well pH has an affect on goldfish health: too low or too high a pH causes the fish to be stressed and if it is stressed it is more susceptable to disease and will not grow.
